Distillation is a method of separating mixtures based on differences in volatility of components in a boiling liquid mixture. It is defined as a process in which a liquid or vapour mixture of two or more substance is separated in to component fractions of desired purity by the application and removal of heat. In this work importance is given to Binary distillation columns. In the Binary Distillation, the feed to the process consist of mixture of two components (A & B) and after the distillation two products will be generated. It is very important to model a distillation column and perform its analysis before the distillation column is practically implemented. Distillation columns are generally considered as chemical systems, for modelling chemical systems one can use mass balance equations.
Introduction
Conclusion
If there is no disturbance in the operating conditions the system is able to achieve steady state purity of the product. From the above response it is clear that it does not achieve the desired purity, this is one of the problem that has to rectify. For this an efficient controlling scheme that can preserve the actual nonlinear characteristics of the practical system is needed.
